1064nm Laser Target Designator Module - 40mJ

PRODUCT DESCRIPTON

The ERDI LASER LDR40K3 is a compact 1064 nm solid-state laser rangefinder and target designator module, pumped by a diode array and designed for precision ranging and reliable laser designation. Featuring high pulse energy, excellent beam quality, and accurate laser coding, the LDR40K3 is optimized for UAV payloads, electro-optical pods, precision guidance systems, and demanding tactical applications.

Key Advantage

1. High-Energy Output with Superior Beam Control
Delivering pulse energy ≥40 mJ with beam divergence ≤0.5 mrad, the LDR40K3 ensures strong energy concentration and stable target illumination at long distances.

2. Accurate and Stable Ranging Performance
With a maximum ranging distance ≥5,000 m, ranging accuracy of ±2 m, and acquisition rate ≥98%, the module provides dependable distance data for mission-critical operations.

3. Precision Laser Coding and System Compatibility
Supports precise frequency coding and user-defined code settings, with laser code accuracy ≤±2.5 μs, enabling seamless integration with a wide range of guided weapon and designation systems.

4. Compact, Lightweight, and Environment-Ready Design
Weighing ≤420 g in a compact form factor, the LDR40K3 operates reliably from –40°C to +60°C and withstands harsh storage and deployment conditions, making it ideal for airborne and field-deployed platforms.
